This error typically arises when the same field name is defined multiple times in the context of an OData entity type, which leads to ambiguity when the OData service is being generated or executed.
  Cause:
  
  Duplicate Field Names: The most common cause of this error is that the same field name has been defined more than once in the same entity type or in the associated data model.
  Inconsistent Naming: Sometimes, fields may have similar names or aliases that can lead to confusion in the OData service definition.
  Model Definition Issues: If the data model is not properly defined or if there are inconsistencies in the underlying data structure, it can lead to this error.
  
  Solution:
  
  Check Entity Type Definition: Review the entity type definition in the OData service. Ensure that all field names are unique within the same entity type.
  Rename Duplicate Fields: If you find duplicate field names, rename them to ensure uniqueness. This may involve changing the field names in the underlying data structure or in the OData model.
  Review Associations and Navigation Properties: If the error is related to associations or navigation properties, ensure that the fields involved do not have conflicting names.
  Regenerate the OData Service: After making changes, regenerate the OData service to ensure that the changes are reflected in the service definition.
  Check for Inherited Fields: If you are using inheritance in your data model, ensure that inherited fields do not cause naming conflicts.
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like SE80 (Object Navigator) or SEGW (Gateway Service Builder) to check and modify the OData service definitions.
  OData Service Activation: After resolving the issue, make sure to activate the OData service using transaction IWFND/MAINT_SERVICE.
  Debugging: If the issue persists, consider using debugging tools to trace the service generation process and identify where the conflict arises.
  Documentation: Refer to SAP documentation on OData services and ABAP programming for best practices in naming conventions and data model design.
